PROCESS OF APPLYING LABELS TO PHONOGRAPHIC RECORDS AND OTHER ARTICLES.

Application filed October 13, 1923. Serial No. 668,359.

To aZZ whom. it may concern:

Be it known that I, Voomrnns \VINFIELD CHALLENGER, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented a Process of Applying Labels to Phonographic Records and Other Articles, of which the following is a specification.

Labels are applied to a phonographic record and like articles during the process of manufacture and while the material is hot. Ordinary printed labels, when applied, expand. and blister.

One object of my invention is to improve the process of applying printed labels to phonographic records and other articles so as to prevent the ink blistering the labels,

A further object of the invention s to provide the label with a highly polished surface, which cannot be scratched in the ordinary handling of the record.

In the accompanying drawings:

Fig. 1 is a face view of a phonographic record, showing a label applied thereto;

Fig. 2 is a detached view of the label; and

Fig. 3 is a diagrammatic view with the parts of the record and the labels assembled between two heated dies, which press the blanks into the form of a phonographic record.

Referring to the drawings, 1 is a phonographic record made of three plies of material 3, '3 and 4:, in any suitable manner. 2, 2 are the labels, located on bot-11 sides of the record in the present instance. The materials, which form the record and the record are placed between two heated dies 5, 5 in a suitable press. The record disk is formed by pressure and the labels are imbedded in the material. In the present instance, the labels are printed on white paper. The ink used in producing a background, as well as the design and lettering, is composed of a pigment and a given amount of varnish. Heretofore, when a label of this character was applied to a record during the process of manufacture the heat of the dies would expand the varnish in the ink and blisters would form on the labels, rendering them Worthless. This objection is overcome by coating the printed surface of each label with casein so that, when it is subjected to heat and pressure, in forming a phonographic disk, for instance, the casein hardens and prevents the varnish expanding and blistering the paper.

Furthermore, the casein forms a hard coating on the surface, which resembles the gloss on the finished record. This surface resists scratching under ordinary use and gives a finish to the label.

Heretofore, it was found necessary to use tinted papers in the manufacture of phonographic labels. By my invention, the body of the label can be white, and different body colors can be printed on the labels in the usual manner so that the designs on the labels are not limited.

While the invention is especially adapted for use in labeling phonographic records, the process may be carried out in applying labels to different devices.

I claim:

1. The process herein described of applying labels to objects, said process consisting in first coating the printed label with casein, then subjecting the label to heat and pressure to apply the label to the object, and causing the casein to harden, preventing blistering of the paper due to the expansion of the material forming part of the ink compound.

2. The process herein described of applying labels to phonographic records, said process consisting in printing the label with ink, coating the surface of the printed label with case-in, assembling the coated label with the other parts that form the record, impressing the label intothe material of the record by heated dies, the heat hardening the casein, which prevents the ink blistering the paper of the label, and giving a polished surface to the label.

8. The process herein described of applying paper labels to articles shaped by pressure and heat, said process consisting in coating the exposed surface of the label with casein, impressing the label into the article when heated to cause the label to adhere thereto, the casein hardening and forming a polished surface upon the label.
